Cleo Quinzel (voiced by Lauren Tom) is a mean little girl that bullies Xion.

She thinks that since she's rich, this makes her better than anyone. But she's wrong. Her posse consists of her only friends Jessica, Amazonia and Lola. Like Diamond Tiara and Silver Spoon, they enjoy bullying Xion. But no matter what, they ALWAYS get taught a lesson at the end.
